You're welcome, ss,
When you find your pictures, then comes the hanging-up part.
The article I am linking here is from houzz.com and is titled "6 Easy Ways to Skillfully Hang Your Art."
This article has some pictures which might give you some ideas, especially if you are considering doing groupings. I had to laugh though because one of the pictures is of frames, all sprayed with gold paint, but with no pictures in them. -- I hope you are not to that point yet. I know you are going to find the perfect pictures for you. But nest-feathering sure can take a while sometimes. Carry on.
